Most people believe that the only way to maintain a sharp mind is by completing intellectual activities such as reading, solving problems or studying new information. However, studies show that physical exercise is actually highly effective in keeping the mind healthy along with the body. These studies reiterate the importance of physical activity in regards to the overall well-being of a person.

Establishing that exercise is essential for brain health is certainly helpful, but determining the type and duration of exercise that can most benefit brain health is also important.

Walking is one of the best physical activities for brain health. A simple walk can increase blood flow to the brain, and studies have found a strong correlation between walking for exercise and maintaining good brain health. One study showed that elderly people improved their memory and ability to learn simply by taking a 20 minute walk every day. Additionally, the study group had a lower risk of stroke as compared to their sedentary counterparts.

Because of the connection found between regular exercise and cognitive function, including at least 20 minutes of moderate physical activity most days of the week is recommended. A moderate physical activity can consist of any of the following: Riding a bike, swimming at a slow pace, walking briskly, jogging slowly, using an elliptical trainer, digging and planting a garden.

Although a person can break their exercise sessions up, a person must engage in moderate exercise for at least 10 consecutive minutes to enjoy the physical and mental benefits of exercise. Two exercise sessions of 10 minutes per day provide the most mental and physical benefits for a previously sedentary person.
